Greek wildfires toll rises to 79 amid search for survivors

At least 79 people died in huge wildfires around Athens, Greek authorities said Wednesday, as rescuers scoured scorched homes and burned-out cars for survivors of one of the world's deadliest fire outbreaks.

Scores of locals and holidaymakers fled to the sea to try to escape the flames as they tore through towns and villages near the capital stoked by 100-kilometre-per-hour wind gusts, devouring woodland and hundreds of buildings.

Greek media have described the disaster as a "national tragedy", while Prime Minister Alexis Tsipras cut short a visit to Bosnia and announced three days of national mourning.

Spokeswoman Stavroula Maliri said authorities knew of "79 dead", surpassing the 77 people killed in the previous deadliest fires in Greece, on the southern island of Evia in 2007.
